Nano Banana 2 AI 圖像生成與編輯器
Google 最新 Nano Banana 模型，發布於 2026 年 10 月 6 日：文字生成圖像與以圖生圖融合於一體，支援最多 14 張參考圖，1K、2K 或 4K 輸出，每張僅需 12 點數起。
什麼是 Nano Banana 2.1?
Nano Banana 2.1 is Google's newest image generation and editing model, announced on October 6, 2026 with the Gemini API model ID gemini-nano-banana-2.1. Google describes it as an update to Nano Banana 2 (Gemini 3.1 Flash Image) that keeps Flash-level speed and cost while improving visual quality, prompt adherence, character consistency and text rendering. Its model card says it is based on Gemini 3.6 Flash, and Google positions it as the more efficient counterpart to Nano Banana Pro.
According to Google's Gemini API model page, the main changes are better realism at 1K, 2K and 4K; fixed tiling artifacts on extreme ratios (1:4, 4:1, 1:8, 8:1) at 2K and 4K; more accurate text and infographic layouts; and up to 14 reference images, with consistency for up to 4 characters and 10 objects.
On Flux1 AI, Nano Banana 2.1 has been live since October 9, 2026 and is the default model in the generator above. You write a prompt, optionally add up to 14 reference images, pick a ratio and a resolution, and get one image in about 60–90 seconds. The same model is available to developers on the Flux1 AI API at the same credit prices.

What Nano Banana 2.1 does well
Google's four headline upgrades, and how each one works on this page.
Cleaner panoramas and tall strips
Google reports better realism at all three resolutions and fixed tiling artifacts on very wide or tall images at 2K and 4K. Here you can pick 1:4, 4:1, 1:8 or 8:1 directly: a 1:8 run at 1K came back at 352 × 2928 px, a 16:9 run at 2K at 2752 × 1536 px.
Text and infographics
Google lists enhanced text rendering and infographic layout accuracy as a key update, and its model card puts 2.1 ahead of Nano Banana 2 and Pro on its infographic tests. Short headlines in quotes, numbered lists and labeled diagrams are where it pays off; render at 2K or 4K when small text matters.
Up to 14 reference images
Upload product shots, faces, logos or style frames and tell the model which image supplies what. Google tunes 2.1 to keep up to four characters and ten objects consistent. References cost nothing extra here, so a 14-image composite costs the same as a plain prompt at the same resolution.
Generate and edit in one model
There is no separate edit mode. With no reference, 2.1 creates from text; with references, it edits or combines them. Set the ratio to "auto" with a reference and the output keeps the input's proportions, which is what you want for background swaps and retouching.
如何使用 Nano Banana 2.1
Four steps from prompt to download. Credits are only spent when a run succeeds.
- 1
Write the prompt
Nano Banana 2.1 is already selected in the panel above. Describe subject, action, setting, lighting and framing in plain sentences, and put any text that must appear in quotes with its position.
- 2
Add references (optional)
Upload up to 14 images to edit or combine. Refer to them by number in the prompt, for example "the jacket from image 2 on the person from image 1".
- 3
Choose ratio and resolution
Pick a ratio from 1:8 to 8:1, or "auto" to follow your first reference. Choose 1K for drafts, 2K for most web use, 4K for print or crops. The credit cost updates before you press Generate.
- 4
Wait, then iterate
A run usually takes 60–90 seconds. You can leave the page; the image lands in your history. Reuse a result as a reference to change one detail, or rerun your best 1K draft at 4K.
Prompt tips for Nano Banana 2.1
Since each run takes about a minute, a specific prompt saves more time here than on faster models. Name the scene, quote the text, number the references.
Nano Banana 2.1 vs other models on Flux1 AI
All of these run on the same credit balance, and the first four are in this generator's model menu.
| 模型 | 适用場景 | Max output | References | 典型耗時 | Credits / image |
|---|---|---|---|---|---|
| Nano Banana 2.1 | Infographics, extreme ratios, multi-reference composites | 4K | Up to 14 | 60–90 s | 12–21 |
| Nano Banana 2 | Fast everyday work up to 4K | 4K | Up to 14 | 10–20 s | 10–21 |

Nano Banana 2.1 vs Nano Banana 2
Google calls 2.1 an update to Nano Banana 2: same 1K/2K/4K range and 14-reference limit, with better realism, prompt adherence, consistency and text, and cleaner extreme ratios. On Flux1 AI, 2.1 costs 12 / 16 / 21 credits against 10 / 14 / 21 for Nano Banana 2, and it is slower here: about 60–90 seconds versus 10–20. Use Nano Banana 2 for fast iteration, 2.1 when text, layout or a wide panorama has to be right.
Nano Banana 2.1 vs Nano Banana Pro
On Google's human-preference tests in the 2.1 model card, 2.1 scored above Pro in every listed category, and Google calls it the more efficient counterpart to Pro. Early independent same-prompt tests are more mixed and still favor Pro for matching a reference face and for signs inside a scene. Nano Banana Pro costs 14 credits at 1K or 2K and 28 at 4K, and returns in 10–15 秒 here.

Good to know before you start
What this page does differently from Google's own apps, and where the model still slips.
Slower here than Nano Banana 2
A run usually takes 60–90 seconds on Flux1 AI, against 10–20 seconds for Nano Banana 2. Draft ideas on a faster model, then use 2.1 for the version you keep.
No Thinking or search controls
Google's API offers Thinking levels (minimal, medium, high) and grounding with Google Web and Image Search. Neither is exposed here, so the model does not look up current facts for you: write verified numbers, names and dates into the prompt.
No mask, brush or chat editing
Google highlights mask-based and multi-turn conversational editing. This generator has no brush or selection tool and no chat thread: you edit with references and one instruction per run, and to continue, reuse the result as a reference.
One image per run
Each run returns a single image. For variations, run the same prompt again or change one phrase at a time so you can see what made the difference.
Proofread the text
Google's model card for 2.1 lists blurry small text at 1K, long paragraphs and left/right confusion as known weak spots. Keep on-image text short, render at 2K or 4K when it is small, and check every word before publishing.
Content rules apply
Explicit or "spicy" sexual content is not supported. Google's safety filters can block prompts or references that break the content policy, and a blocked run is refunded.
